CAS :<p>Indocyanine green is a fluorescent dye with a variety of applications in medical imaging. It has been used to diagnose and evaluate the activity of cancer cells and brain functions. Indocyanine green has also been used as an angiographic agent for diagnosis of solid tumours. In addition, it can be used to evaluate liver function and the blood flow in the brain. The biological properties of indocyanine green have not yet been fully elucidated, but it is known that it binds to hepatocyte-like cells in culture and is found at high levels in human serum. This dye shows fluorescence when bound to DNA or RNA, which indicates its possible use as a molecular probe for detecting carcinoma cells. <br>Indocyanine green is a STT3B inhibitor and has been shown to prevent α-amanitin toxicity in mice (Wang et al, 2023). This means it could be a possible antidote to poisoning by Amanita, such as death cap mushroom Amanita phalloides, which is the cause of over 90% of fatal mushroom poisoning.</p>Formule :C43H47N2O6S2·NaDegré de pureté :(%) Min. 95%Couleur et forme :Green PowderMasse moléculaire :774.96 g/molHydroxy naphthol blue

CAS :<p>C.I.Direct green 28 is a site-specific fluorescent dye that binds to guanine nucleotide-binding proteins, which are involved in the regulation of heart function and signal pathways. The α subunit of these proteins has been shown to bind C.I.Direct green 28, with a hydroxyl group on the amino terminus and an ubiquitin ligase at the carboxyl terminus. This binding inhibits polymerase chain reaction (PCR) amplification by interfering with the ubiquitin proteasome pathway, which results in decreased light emission and hematopoietic cell production. This activity is hypothesized to be due to the inhibition of ATPase activity by C.I.Direct green 28, which leads to decreased phosphorylation of E1A-activating enzyme and increased phosphorylation of E2F-repressing enzyme, preventing DNA replication through transcriptional activation of erythroid transcription factors and halting progression through G1/S phase</p>Degré de pureté :Min. 95%Disperse yellow 56, technical grade
